ELECTRIC COOKING APPARATUS. I

Application flled il'une 13, 1923. Serial No. 645,063.

To all whom it may concern:

Be it known that I, MASAO SAEKI, a Japanese subject, residing at Tokyo,Japan, have invented certain new and useful Improvements inElectricCooking Apparatus, of which the following is a specification.

My invention relates to electric cooking apparatus, especially toenclosed electric cooking apparatus,and has for its object to provideelectric cooking means whereby electric energy may be most economicallyutilized for cooking and with a minimum loss of heat. h v

My, invention afi'ords an apparatus 1n whichfelectricheat'is conductedor generated in a totally enclosed phamber', the surrounding wall of thechamber being comn this chamber, the cooking vessel contain ing food isplaced and the cooking is done above the atmospheric pressure.

The attacheddrawing shows a section view of cooking'apparatus embodyingmy invention. v

In the embodiment shown in the drawing, thewall of the enclosedapparatus" is composed of double walls filled between I with good heatreserving or insulatin materials. The sidb wall 1 and bottom wal 2 ofthe apparatus are made in a single body and the top wall 3 forms ahinged cover by means of the 'oint 4:. An insulatin sup- 'vided with anelectric heating element 6.

bore 8 fixed to the side wall 1 or on the insulating sup'porter5. Cover9 of the kettle 0 cover 9, may be opened or closed throu h the joint 4.The cover 9 is' ressed ti ht y in place against the body 0 the kett e bythe spring 10 when the cover 3 is closed. In some cases the cover 9 maybe hinged to the kettle according to my invention as this feature is notan essential part of my invention. The steam pipe 11 which passesthrough cover 9 and the top wall 3 is fixed to the top wall 3' and thispipe slidablyfits letely provided with heat insulating means.

A kettle or pot 7 rests on supporting mem-' in the opening in the cover9. At the' top of this tube 11 a safety valve 12 is provided; 1 thisvalve may act as an electric circuit con trolling device in connectionwith its stationary contact 13. To give an audible signal when thepressure in the kettle increases to a predetermined value, a whistle 15is provi ed. t The circuit of, heating coil 6 may be opened by theopening of the valve 12. Instead of a whistle 15, an electric bell which60 is energized through a circuit (not shown) closed y the engagement ofvalve 12 with the stationary contact member 13'may be 4 provided to givea si a1, if desired, when the cooking is finishei As described above,my-invention relates to an electric cooking apparatus characteriz'ed bythe fact that said apparatus con tains anelectric heating element and acook-. ing kettle or pot sealed in an enclosed chamher whose surroundingwall is completely provided with heat, preserving means. The apparatusaccording to my invention has the advantages that the consumption ofelectric energy may be reduced to a minimum, there being substantiallyno heat dissipatiomthat the heat can be stored for a considerable timeafter the electric current is cut OE, and that the'cooking can be doneabove atmospheric pressure.

. What I claim as new and desire to secure 7 y Letters Patent of theUnited States, is, port 5 is place on the bottom 2 and 1s pro- 1.Electric cooking apparatus comprising a heat insulated container, acover therefor, a cooking vessel in said container, a cover 35 therefor,and a resilient connection between said covers whereby said cookingvessel is sealed b the closing of said container, and electriceatingmeans in said container for said cooking vessel.

2. Electric cooking apparatus comprising a heat insulated container, acover therefor, a cooking vessel in said container, electric heatingmeans in said container for said cooking vessel, a coverfor said cookingvessel, an a resilient connection between said covers whereby saidcooking vessel cover is I pressed tightlyin place so as to seal saidcookin vessel when said container is closed.

3'. E ectric cooking apparatus comprising a. heat insulated container,:1. cox er therefor, and a resilient connection between said covacooking Vessel for said contalner, electric ers whereby said cookingvessel cover is heating means in said container for said pressed tightlyin place to seal said cooking 1 cooking vessel, a cover for said cookingvesvessel when said container is closed.

sel carried by the cover of said container so In witness whereof, I havehereunto set that said cooking vessel is opened and my hand this 19 dayof Ma 1923. closed simultaneously with said container, 7 MA A0 SAEK'I
